Kits Coty House,
on the road between Rochester and Maidstone, a well-known cromlech, is Katigerns or Kitigerns coty housethat is, the house or tomb of Kitigern, made of coits or huge flat stones. (See HACKELLS COIT and DEVILS COIT.)
Katigern was the brother of Vortimer, and leader of the Britons, who was slain in the battle of Aylesford or Epsford, fighting against Hengist and Horsa. Lambarde calls it Citscotehouse (1570). The structure consists of two upright side-stones, one standing in the middle as a support or tenon, and a fourth imposed as a roof. Numberless stones lie scattered in the vicinity. Often spelt Kitts Cotty House.
